Troubleshooting
Problem
After upgrading firmware or making changes in network configuration, the network interface is operationally down and nonmanagement network traffic to all interfaces is blocked. This behavior is designed to prevent the accumulation of errors that might not cause immediate issues but, when uncorrected, might lead to undesirable behaviors and increased uncertainty during problem determination.
Symptom
Invalid network configuration produces the following results:
- The incorrectly configured network interface (Ethernet, VLAN or link aggregation) is set operationally down.
- By default, nonmanagement traffic to all network interfaces is blocked. Only management traffic over Telnet, SSH, web management interfaces (WebGUI and Blueprint Console) and the XML management interface is permitted. Production traffic is blocked.
- The following error message is displayed in the WebGUI or CLI:
At least one network interface has an invalid configuration. Until corrected, nonmanagement traffic is blocked.
In the CLI, the error message is displayed when exiting a configuration mode. In the WebGUI, the error message appears in a red warning box on every window. Note, however, that the Blueprint Console does not support display of this error message.
